Brief description The aim of the project is to identify poorly structured subsoils developed in regolith materials in rehabilitated bauxite mines and develop procedures for minimising the effects of poor soil structure on tree growth. Well structured regolith types will also be identified as sites requiring less ripping. Large-scale field trials will be established to examine the impact of ripping on different regolith types. Methods will be developed to enable prediction of regolith structure based on instumented rippers, drill hole data and remote sensing. Greater success of revegetation practices and a decrease in annual ripping costs ($1.3 m) are anticipated.
